Alarms and Emergency
Conditions
The alarm thresholds for the system are set as described in the normal
operating mode. When an alarm condition is obtained the red LED on the
signal processor will light up. This will go out when the alarm condition has
cleared. If the analyzers are linked to the Integrated Emission Monitoring
package that remotely monitors the system, the alarm will be displayed on the
IEM system monitor. When the condition has cleared the fact that an alarm
condition occurred will be recorded by the software. The 4 to 20 mA output
from the analyzer will also alter according to the pollution levels detected.
Emergency Shutdown
Procedure
The same as normal shutdown - remove power from the power supply and
the whole system will close down. Close the isolating valves if required and
stop the flow of air to air purges.
Isolation Procedure Shut off power to the power supply. Shut off compressed air to the air purges
and shut the isolating valves.
Interface with Integrated
Emissions Monitoring
System

via a serial data line, central control unit (CCU) and pc, then details of
configuration of this system are to be found in the operating manuals
OPS.087 (Communication Equipment) and OPS.016 (IEM Software).
